Question: My father was diagnosed with Anaplastic Astrocytoma. He had surgery, radiation and has now just completed his 3rd cycle of Temodar. He is on Decadron and Dilantin. His MRIss show no growth of the tumor but he still is experiencing edema so we had to increase the Decadron dosage. This seems to be common from what I have read, however, I am wondering if there are any averages or information on this or if this swelling will ever decrease since its been over 4 months since radiation and he seems to be responding to the Temodar.

Answer:01/09/2002The amount of edema can be individual but can also be affected by dosage
and time over which it is administered. If IMRT or a radiosurgical boost is
given, edema can last longer.
